Well, honey, a galvanometer shows one-sided deflection in a meter bridge experiment because the galvanometer is connected in series with the unknown resistance being measured. The current flows through the galvanometer in one direction only, causing it to deflect to one side. It's just the way the cookie crumbles in the world of electrical measurements, sugar.

What is effect of interchanging the galvanometer and driver cell in meter bridge?

Interchanging the galvanometer and driver cell in a meter bridge would reverse the deflection of the galvanometer. The direction of current through the bridge wire would also change, affecting the balance point. The new balance point will now represent a different ratio of the unknown resistance to the known resistance.


Why is the lamp and scale arrangement in a ballisitics galvanometer at a distance of 1 meter from the galvanometer?

The lamp and scale arrangement in a ballistic galvanometer is placed at a distance of 1 meter to ensure that the deflection of the galvanometer caused by the current pulse is accurately measured. Placing it at this distance allows for the angular displacement of the galvanometer's coil to be proportional to the charge passing through it, aiding in the precise measurement of the current pulse's magnitude.

What is the deflection sensitivity of a cathode ray oscilloscope?

What happens to a galvanometer when a magnet is flicked across the coil?

It should deflect to the left (negative) based on the experiment I did a few days ago in lab but I could be wrong. ============================= Doesn't that depend on which end of the coil goes to which end of the meter ?? After you finished the experiment and made note of the meter's deflection, you could leave everything exactly as it is, but get up, walk around to the other side of the table with the magnet, insert the S-pole into the other side of the coil, and I guarantee the meter would deflect in the opposite direction. The configuration is not adequately specified in the question.


What kind of meter is created when is shunt is added to a galvanometer?

A galvanometer with a low resistance shunt in parallel makes an ammeter.


What is coil galvanometer meter and its application?

A coil galvanometer is a type of device that uses a movable coil in a magnetic field to measure electric current. As the current flows through the coil, it experiences a torque that causes it to move, with the deflection indicating the strength of the current. These galvanometers are used in applications such as measuring small currents, detecting the presence of current, and in analog meter movements.


What is steady deflection?

When battery key and galvanometer key are pressed together ..throws comes out on the meter scale which goes on either side and stop there..that is steady deflection...


What is Ballistic galvanometer Explain its construction?

A ballistic galvanometer is used by electricians to measure an electric current. It is commonly used to test whether or not an electric current is present. A ballistic galvanometer consists of a meter that is attached to two probes, one positively charged and one negatively charged. This keeps the user from being electrocuted when an electric charge is present.


How do you study earth's magnetic field using a tangent galvanometer?

The expression for tan @ is F/B Here F = mu not n I / 2a mu not = permiability of air which equals to 4pi x 10-7 H/m n = number of turn in the TG a - radius of coil in TG in meter I = the current flowing through in ampere B is the earth's magnetic field. Hence B = F / tan@ Here @ is the angle of deflection in the TG when two perpendicular fields are applied. Here one is earth's magnetic field whose induction is B tesla and F is the magnetic field produced due to flow of current in the TG coil

How do you convert a galvanometer to an ammeter?

A galvanometer is an instrument used to measure and detect electric currents. While that seems a lot similar to an ammeter, it only deals with measuring relatively small or mediocre currents. Although an ammeter is now much preferred due to its more accurate, faster, and advanced readings, there is a way to "convert" a galvanometer to function like an ammeter. A current separator or divider, known as a shunt, allows a simple meter to be calibrated (adjusted) to measure larger currents. The shunt, parallel to the coil of your galvanometer, allows more electric currents to circulate around the circuit, thus obtaining more current.
